What audio hardware do you have in your system? If you can, please download and run 
http://www.alsa-project.org/alsa-info.sh, and reply to me off list with either the URL to the output from the 
script, or the contents of the file that alsa-info.sh creates, so we can try and fix your mute audio on boot 
problem.

As for getting audio up, open a terminal, and follow these steps exactly. It appears your master volume is 
turned up, but muted, so this should be relatively simple to unmute, as follows.

In a terminal, run alsamixer.
Once alsamixer is loaded, press the M key.
Press escape to exist, and hopefully your audio is unmuted. If you want confirmation, get another dump of 
amixer output, and reply to this message with it attached so I can have a look.

Hope this helps.
